Information for Test on chs 4.4-5.6. Review multiple choice questions on www.aw.com/walker
from chs 4 and 5. Problems to be able to do:
-Projectile motion when an object is shot from a height (ie cliff, table top, roof, etc) . You will be given angle of shot and initial velocity (resultant). and height off the ground. Steps to solve: 1) break initial velocity into x and y velocities using trig. 2) determine final velocity in y direction remembering the d in y direction is below the origin (therefore negative) and the final velocity in the y direction is also negative because it is in the opposite direction from the orginal y velocity. (You can avoid this step if you use the quadraidic equation - go right to step 3) 3) calulate t. Time is the same for both the x and y components. 4) use time to solve for range remembering the velocity in the x direction is CONSTANT and follows the equation v = d/t. (no acceleration, no Big 5)
-Newton's second law - F=ma. You will be given mass and some other values (vf, vi, d, or t) to solve for a.
-Forces acting on a slope - Remember to shift your origin so that it is parallel with the slope.
